Our ratings (out of 10)

1 to 10, compared with the whole market. Each says what it's based on. How we score

Weight

From maker's figures 6/10

How much it adds to your pack. 6: A bit better than average.

Montane's UK and EU pages give 200 g with no size; its US page gives the same weight in ounces, about 201 g, in the same band. 200 g is in the 200–239 g band, which is the 3 band. GO Outdoors and Blacks copy gives the same 200 g.

Warmth

From maker's figures 5/10

How much the fabric insulates next to your skin. Heavier fabric is warmer and slower to dry. 5: Does the job. Average for wild-camping gear.

Montane's UK and EU pages give Apex Thermo at 160 g/m² (its US page calls it Apex Thermo Eco, with the same figure). 160 g/m² is in the 150–189 band, which is the 3 band.

In short

Good for

  • Cold-weather hillwalking, mountaineering and winter wild camps as a warm next-to-skin layer, which Montane pitches for sub-zero use
  • Sleeping in on cold nights, with the brushed back against the skin
  • Multi-day winter trips where one synthetic top is worn and rinsed

Strengths

  • 160 g/m² brushed Apex Thermo fabric: a published figure, in the 3 band for warmth
  • Quarter-length YKK zip for venting, with a low-profile collar
  • 4-way stretch and flatlocked seams, per Montane
  • Covered by Montane's lifetime guarantee against faults in workmanship and materials

Weaknesses

  • 200 g is mid-range for weight (score 6), and Montane gives no size for it
  • The zipped collar and brushed fabric add bulk: it is a cold-weather top, not a summer one
  • No independent hands-on test of the current top found, so comfort, odour and durability are estimates, not reviewed scores
